Title: Frequency Divider
IPC: H03L7/22
Filed: 1966-06-15
Abstract: 1,155,371. Automatic frequency control systems. HEWLETT-PACKARD CO. 15 June, 1966 [19 Aug., 1965], No. 26810/66. Heading H3A. In a frequency divider the input f x  is fed to a pair of sampler type harmonic mixers 11, 13 which produce outputs related to the instantaneous amplitude and phase of the applied signal at the sampling instants, the mixer 11 being used to phase lock an oscillator 15 at a subharmonic f 1  of the input, and the mixer 13 providing the required output at terminal 21. The division ratio m is determined by the ratio of a frequency divider 33 which divides the output of oscillator 15 to provide a reference oscillation for a phase loop which locks an oscillator 19 to a frequency # 1  ##, where m## = # 1 , the oscillator 19 providing the second input to mixer 13. A filter 27 tuned to #f disables the loop when oscillator 19 is well off tune and allows a search oscillator 35 to operate. The amplitude of the final output is measured by a detector 37 which controls a gain control unit 10 in the output of mixer 11 which is used to control the frequency of oscillator 15 and which is also fed to a summing unit 30 to control the frequency of oscillator 19, thereby preventing the amplitude of the input signal affecting the phase locks. The input frequency f x  is a multiple n of the frequency f 1  of oscillator 15, and n can be determined by changing over switch 42 to supply a reference frequency # o  from oscillator 44 to phase detector 31. #f is then equal to f o , and the output frequency at terminal 21 is nf o  and is passed through a gate 46 controlled by oscillator 44 to a counter 48.

Patent GB-397317-A (GB)
Title: Process for producing a permanent suspension of oil in waters
IPC: B60S3/04
Filed: 1932-10-01
Abstract: <PICT:0397317/III/1> A permanent colloidal suspension of oil in water is produced by injecting oil in minute quantities into a high pressure stream of water, the oil and water being heated approximately to the same temperature, e.g. to 110-160 DEG  F., and the oil being under a slightly higher pressure than the water.  The oil and water may be brought approximately to the same temperature by utilizing the heated water as a heating medium for the oil.  The suspension may be used as a cleaning fluid for removing oil, grease, and dirt from locomotives, railway cars, machinery, and the like.  A suitable apparatus for producing the emulsion comprises an oil tank 10 through which passes the hot high-pressure water supply pipe 15. Where the latter leaves the oil tank it is divided, connections being made with the bottom of the oil tank in order to force the oil upwards, and with a spring-loaded valve 30.  The water passing the valve 30 into the pipe 28 is at a somewhat lower pressure than the oil in the tank.  The oil is therefore caused to flow up the tank 10, down the supply pipe 22 and into the water stream in pipe 28, where emulsification takes place.  The emulsion enters the spraying nozzle by way of the pipes 29, 35, 36.  Specification 14933/15, [Class 138 (i), Washing and cleaning buildings &c.], is referred to.

Abstract: 1,074,339. Punching - machines. R. SCHWORER. June 29, 1965 [July 1, 1964], No. 27534/65. Heading B4B. In a machine for making a row of holes in a pack of sheets comprising a work-table 1, a vertically-movable clamping beam 2 and a vertically-movable drilling complex equipped with a row of drills 16 spaced equidistantly from each other, the drilling complex being continuously displaceable in the axial direction of the drills and displaceable stepwise in a direction normal to the drill axes, the work-table and the clamping beam each having a row of guide holes 3 or 4 for the drills and the distance between each two neighbouring drills being a multiple of the distance between the axes of each two neighbouring guide holes, each drill is a hollow tubular punch drill the cutting edge 16a of which tapers inwardly to form a frusto-conical hollow 17a. The drill chuck 7 has an opening 7a through which the punched-out chips pass to a channel 8 to which a suction device is connected. The drive pulleys, e.g. 9a are operated together in groups of five by means of an endless belt and a driving pulley driven by its own electric motor and each belt being provided with a tensioning belt which can be retracted by means of a manually-operable spring-influence lever.

Title: Advertisement writer
IPC: B44B3/06
Filed: 1930-09-15
Abstract: 356,492. Writing-machines. PEIN, H., 8, Kohlh÷kerstrasse, Bremen, Germany. Sept. 15, 1930, No. 27560. [Class 146 (iii).] An automatic writing device comprises a travelling flexible steel strip 1 having undulating edges against which bear rollers 2, 3 mounted on pivoted levers 4, 9. The spring-pressed lever 9 is fixed to a spindle 12 carrying a tubular vector arm 13, and the lever 4 is connected by a cord 7 passing round pulleys 20 in the spindle 12 to a spring extruded rod 14 reciprocatable in the arm 13. The writing instrument 18 is held either vertically or inclined, its lower end passing through an eye in the rod 14, and the upper end lying in a ring at the extremity of a fixed member 32. The curves on the edges of the strip 1 are so shaped that the angular oscillation of the arm 13 together with the in and out movement of the rod 14 produces the required script. The curves on the strip 1 are determined by developing the ordinates and abscissµ of the script and flattening the curves, the abscissµ curve being given a backwardation to compensate it for the continuous movement of the band 27 on which the writing is done. Fig. 13 shows a pen 18 surrounded by a hollow model of a hand which shares in its oscillating movements, the curves on the strip being rectified to conform to the angular disposition of the pen. The strip 1 may be prevented from lateral movement by perforating it longitudinally and engaging the perforations with the teeth 38 of a laterally fixed rotary disc 39, Fig. 14 a, a grooved roller 43 bearing on the opposite side of the strip to press it up against the disc 39. The pen 18 may be raised from the paper 27 at intervals by lines of perforations in the strip 1 which allow a toothed disc and its supporting spring-pressed lever to rise and lift with it the spindle 12 and the pen. The strip 1 may be built up by inserting short strip lengths in lateral slots in the links of a chain perforated down its middle to engage the disc 39. The strip 1 may be wound on and off two reels, or may be endless and lie in folds between the reels. The writing band 27 is guided between grooves 28, 29 and is geared to the strip 1.

Abstract: 459,709. Generating combustion products under pressure. SILURIFICIO WHITEHEAD DI FIUME SOC., ANON., Fiume, Italy. Oct. 12, 1936, No. 27643. Convention date, Oct. 11, 1935. [Class 51 (i)] A device for igniting a combustible mixture in the heaters for engines of automobile torpedoes comprises chambers for two or more cartridges and separate percussion devices for the different cartridges actuated successively at predetermined intervals. As shown, the device comprises two elements 1, 1<1> connected by a collar 2, and is adapted for igniting three cartridges in succession arranged in the chambers 3, 3<1>, 3<11> of the element 1<1> corresponding chambers being provided in the element 1 containing the firing mechanism. The element 11 is arranged in the heater so that when the regulator is opened compressed air enters at 14 through the passages 13, 15 to the top of the spring-pressed piston 5 in the chamber 3 of the element 1. The piston 5 slides downwardly over a piston 6 which carries by means of a pivot 8 bell-crank levers 9 held in the position shown by a spring 11 and in engagement with a collar 10. Upon reaching the levers 9, the piston 5 releases them from the collar 10 and the lower arms of the levers move forward under the influence of the piston 6 and spring 7 to engage the percussion device 12 and fire the cartridge to ignite the combustible mixture in the heater. As the piston moves down in the cylinder 3 and slightly before the release of the percussion device, a port 18 is uncovered to permit pressure air to pass to the top of the piston 5 in the chamber 3<11> to actuate the percussion device therein and fire the second cartridge. Pressure air is subsequently admitted to the top of the piston 5 in the chamber 31 through the port 20 to fire the third cartridge. The interval between the successive ignitions may be regulated by suitably selecting the position of the orifices of the passages 18, 20 or by giving the passages suitable dimensions.
